Divers seeking great value will appreciate Thermoprene's balance of performance and price. This new material delivers greater flexibility and improved features not found in standard neoprene wetsuits, yet at a reasonable price. Thermoprene is crafted from a high quality 100% stretch neoprene sandwiched between a low pill jersey with lycra trimmed edges for extra durability and enhanced comfort. A revolutionary one-way flow vent purge valve vents regulator exhaust away from the hood while preventing cold water entry. All seams are double glued and blind stitched for durability and to keep the cold water out. This versatile piece is most often layered under your fullsuit for extra core warmth, but can be worn alone, or in any configuration you can think of. 1yr Warranty
